• FYI (For Your Information) is likely to crop up when you are given irrelevant information from your colleagues in the form of email, memos and corporate manuals.
• COB (Close of Business) usually surfaces when your supervisor requests unrealistic demands of you such as "I want to see this report completed COB, or else?"
• CYA (Cover Your Ass) is everybody's favorite. When an employee is required to cover his ass, in general, it's to prevent blame if someone else made an error. CYA requires one to get proof that he didn't make the mistake.
• PTO (Paid Time Off) is for the purpose of rest, relaxation and a planned interruption from the workplace or to attend to personal affairs.
• V/M (Voicemail) is another description for a message left on a telephone answering machine. It is used as an alternative to traditional means of office communication like face to face interaction.
• THX (Thank You) is even abbreviated in corporate America and unfortunately whether it's used in its brief form or long hand, you won't see or hear it enough.
• MD (Managing Director), VP (Vice President) and EA (Executive Assistant) are job titles and supposedly reflect ranking within an organization. Yet titles in the U.S. workplace are elusive and rarely do they reflect a person's role. Americans can even make a job sound better than it actually is. For instance, an executive assistant is perhaps more commonly known as a secretary in Europe.
